Jabsco V50AJ-115N-3A Sensor Max II 12V 5 GPM 40 PSI Pressure Pump
The Jabsco V50AJ-115N-3A is a Sensor Max II freshwater pressure pump rated at 12V, 5 GPM at up to 40 PSI. Instead of a mechanical pressure switch, it uses an electronic sensor to detect demand, giving smoother startup and shutdown cycles at the tap.
This automatic demand pump turns on when a faucet or fixture is opened and shuts off when it's closed, supplying pressurized fresh water throughout the boat without a separate accumulator tank in most installations.
